Answer:

21.4%

Step-by-step explanation:

You would pay back a 21.4%

The simple interest rate on the loan of $1400 is approximately 21.4% per year.

The simple interest can be expressed as:

A = P( 1 + rt )

Where A is accrued amount, P is the principal, r is the interest rate and t is time.

Given the parameter:

Principal P = $1400

Accrued amount A = $2000

Time t = 2 years

Interest rate r =?

Plug these values into the above formula and solve for the interest rate.

A = P( 1 + rt )

[tex]r = \frac{1}{t} * ( \frac{A}{P} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = 0.21428[/tex]

Convert r decimal to R a percentage

R = 0.214 × 100

R = 21.4% per year

Therefore, the rate is approximately 21.4% per year.

Hey there!

Remember, equivalent means equal.

So we need to find some fractions that are equal to 4/7 and 3/5.

We can easily do that.

First, let's take 4/7.

Let's multiply the top & bottom by 2:

8/14

4/7 and 8/14 are equivalent.

Let's multiply the top & bottom by 2:

16/28

We can keep multiplying...

Also, there's no reason why we cannot multiply by 3, 4, 5, 6, 7, 8...

In other words, there are infinitely many fractions equivalent to 4/7.

Same with 3/5:

6/10, 12/20...

Hope everything is clear.

Let me know if you have any questions; if so, please ask.

Answer:

Step-by-step explanation:

The question may be answered easily by first determining how far we would ride the bike in 1 hour. Riding the bike 12 mph (miles per hour) for one hour, we would ride the bike 12 miles.

Since 20 minutes is 1/3 of a hour, divide 12 by 3 to find out how far the biker traveled in 1/3 of the time:4 miles. that is the answer and the steps!!

Answer:

21

Answer:

x = 30 over 11

Step-by-step explanation:

6(9x-5)-4(3+2x)-3(8x-20) = 24

54x-30-12-8x-24x+6 = 24

22x = 24+36

22x = 60

then divide both sides by 22

x = 30 over 11

Answer:

368 cm²

Step-by-step explanation:

Bottom: 12 * 10 = 120 cm²

Front and back (square): 2 * (10 * 10) = 200 cm²

Front and back (triangle): 12*8/2 = 48 cm²

Total = 120 + 200 + 48 = 368 cm²

6°F

Step-by-step explanation:

6+ -1 =5

There are 6° F warmer was it in Chicago than Minneapolis.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

We have to given that;

On New Year's Day, the temperature in Chicago was 5°F.

And, That same day, the temperature in Minneapolis was - 1°F.

Hence, The temperature warmer was it in Chicago than Minneapolis is,

⇒ 5° F - (- 1)° F

⇒ 6° F

Thus, There are 6° F warmer was it in Chicago than Minneapolis.

Answer:

17

Step-by-step explanation:

After a week he can expect 17 calls.

Given that,
A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent.
This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days.
How many phone calls should she expect after a week is to be determined.

The function which is in format f(x) =aˣ where a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).

Here,

in 1 week = 7 Days
Now,
D = x
y = 30(0.92)ˣ
now put x = 7
y = 30(0.92)⁷
y = 30 * 0.55
y ≈ 17

Thus, After a week he can expect 17 calls.

I think it is x=-4

Step-by-step explanation:

Step 1: Subtract 7x from both sides.

5x+10−7x=7x+18−7x

−2x+10=18

Step 2: Subtract 10 from both sides.

−2x+10−10=18−10

−2x=8

Step 3: Divide both sides by -2.

-2x/-2=8/-2

The correct option is (D)

The slope of a line indicates how steep it is calculated mathematically as "rise overrun". It calculates the rate where the variable y changes when the relevant variable changes, and the further calculation can be defined as follows:

Given Points:

[tex](-4,-2) , (-2,-10)[/tex]

To find:

slope (m)=?

Solution:

[tex](-4,-2),(-2,-10)\\x_{1} =-4\\y_{1} =-2\\x_{2}= -2\\y_{2}=-10\\[/tex]

Using formula:

[tex]slope(m)=\frac{y_{2-} y_{1} }{x_{2-} x_{1} } \\=\frac{-10-(-2)}{-2-(-4)} \\\\=\frac{-10+2}{-2+4}\\=\frac{-8}{2} \\=-4[/tex]

Therefore,  the slope is "- 4".
